During feed feeding, many farmers will find that during a certain period of time, fish that eats around the table is much less than the actual stock, or no fish at all. Sometimes there are fish to eat, eat for a few minutes to leave the table, do not return, it does not reach 80% full. Practice has proved that improving fish anorexia can effectively promote fish growth and development.
Improve methods:
1. Correctly domesticating fry and fingerlings. With the right proportion, the specifications of different species are more consistent to avoid the adult fish from mixing in; thoroughly remove the wild fish.
2, according to the disease to take the appropriate treatment program. Bacterial infections generally use a combination of oral administration and external injection, and external preparations may use chlorine preparations. Oral medications selected furazolidone, fluoride acid and so on. The trichlorfon and levamisole can be used for internal deworming caused by intestinal parasites. The ectoparasite can use 0.2 g/m3 water concentration of ferrous sulfate in combination with copper sulfate, trichlorfon, and other anthelmintic drugs to kill, kill parasites, eliminate mucus, and restore sputum respiratory function.
3, improve the water environment. One is the lack of oxygen in the water, water quality should be thin to promote algal reproduction, generally 2 kg of urea per acre, superphosphate 1 kg per mu. If the effect is not ideal, use it once a week and halve the amount. Excessive water quality results in an oxygen-depleted floating head, which can be prevented by reference to the floating head method of fish, or by using algaecide such as chelating copper to remove excessive algae. The second is toxic ammonia, nitrite, heavy metal ions, residual pesticides in the water, high hp values, etc., which cause stress response in fish. Usually, old water can be discharged and new water can be added. The use of water quality improver can adsorb toxic substances. The use of strong oxidizing agents to promote the transformation of ammonia and other toxic substances; the use of microbial agents such as photosynthetic bacteria to improve water quality. All these measures can eliminate the adverse reactions and the fish can resume eating.
4, choose high-quality feed. High-quality feed is rich in nutrients, amino acid balance, rich in unsaturated fatty acids, vitamins, and minerals, all of which will increase fish appetite, restore food and promote fish growth and development.
